Question about LG Televison & Video

Open Question

Hi, I have a LG80fr 32 inch LCD TV, it's 1 year old (out of warranty) I am facing issues with turning on, Once you start it it takes time to start, recently it start on after a very long time, works fine while running.but takes very long time like 2/3 hrs, sometimes it doesn't start also. Is it something to do with the capacitor coz I checked the entire powerboard and found(visually) that none of the capacitor is brusting or swollen ..... please help me fix this .....

SOURCE: ESA 42 Plasma picture problem

The power supply is having difficulty. The typical cause is underated electrolytic capacitors. I would examine all the caps (round cylindrical cans) in the power supply and see if any of them are bulged. Not a bad idea to just replace all of them with better rated parts.
These type of caps have all kinds of specs. Not just voltage and capacity, but also temperature, case size, and obtuse stuff like dissipation factor. Most all power supplies use switching type designs that run at serious frequencies (not the old 60 hz - more like 50khz) that stress out these electrolytic caps and many circuit designers (or their cheap bosses) don't specify the better parts. Replace them with the same capacitance, but higher voltage, and higher temp parts (hopefully they will not be too big physically).
Ya, I know you paid $$$ for this TV and they scrimped on cheap parts. Yup, the more expensive a product is, the more pressure the bean counters put on keeping the price down.
Hope Ya Fix It.

I had the exact same problem and I fixed my Westinghouse 32 inch by replacing the power supply. You can purchase it at

SOURCE: Vizio LCD 37 Inch Turns Off Randomly

I had a similar problem with my 32 inch plasma tv. I called vizio's
1 800 number and the guy said to unplug the tv from the wall and hold down the power button for a minute and then plug the tv back in outlet and turn on. And it works I guess from what I understood from his heavy accent was that the tv retains power and this resets it somehow. hope that was helpfull!!

Tv is on with no picture or sound, only 4 months old!!


Hello
The power supply regulator board to your set has the fault. If you try to open the set, or try to repair it by yourself, the warranty will void. The set must have warranty as it is new. Why do you spend for it? Just contact the nearest authorised service center for Sceptre. the components in this set will be very hard to get from open electronic spare part market, and will costly too.

If it is under a year old, do not attempt to repair it, call the manufacturer it should still be under warranty. Sounds like a mainbord issue but again let the warranty take care of the repairs.

My 20" rca 20f424t cuts


That sucks about your tv. Mine just turned 3 years old. Never had a problem with it. But you seriously can't expect wal-mart to take back and exchange a 3 year old tv. Come on. That would be stupid for walmart to do. Even RCA prolly dosent do more than a 1 year warranty. Unless you purchased the warranty from walmart, it will be cheaper to just get a 19 inch lcd tv now. Cheapest I see them on sale for is only $99.99

I have a black approx 12 inch streak on the left side(facing tv) of my flat screen Bravia Sony TV . It is approximately 3 years old. It started as a brown panel..then became a fine lined multy colored...


sadly you have a bad panel. Sony panels carry a two year warranty.
your best hope is to call Sony and ask for a warranty extension to cover the cost of the part.

Olevia 32 inch tv turns itself off after a min everytime i turn it on its 4 years old? what do i do


Aside from trying different power cords, I'm afraid there isn't much you can do with an LCD TV with a power issue. Since it's four years old, I'm assuming it's no long under warranty. Did you purchase it with an extended coverage plan or anything?
Sorry to be the bearer of bad news. Hope it helps, though!

I have a 46 inch Samsung LCD model number LN-T4665F and I have been having issues w/ the power/ clicking sound! It used to turn on and clicked a few times now just clicks all the time and doesn't turn on...


1. It is not a two years old TV, but a 9 years old one.
2. The common problem of the symptoms is a defective main power supply, you may check to see that are there anny "Pup-Up" electrolytic capacitor on the power supply, if there is any, replace them, you may fix up the TV

Insignia lcd 37''powering off and right back on by itself!


Hi Ed,
Since the TV is less then a year old and still under manufacturers warranty, I would suggest to take back to the vendor to get it fix because this LCD behavior is not going to get any better.
The failure on this TV is related to a power supply in most cases if the TV is turning OFF by itself or needs to be unplug to let cooldown and it works afterward.

Dell 32 inch LCD Tv volume and menue problems


We also have a 32" LCD Dell flat screen tv #W3201C that has no sound. It's about 2/12 yrs old. One speaker started having a problem and we disconnected it. That was a couple weeks ago, now there is no sound at all. Dell should not be let off the hook so easily. Obviously there is a problem with the tv and it should be Dell's responsibility to make it right. Does anyone know if a class action suit has been initiated?
